Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

Researchers have harnessed nonlocal artificial materials to create optical systems that emulate parallel spaces, wormholes, and multiple realities. A single material acts as two distinct optical media ...

Blurry light from lens imperfections is a problem everywhere, from microscopes to telescopes to smartphone cameras. Using a ...

Optical materials and elements, considered as a physical system, comprise engineered media and components that manipulate electromagnetic radiation in the optical frequency range through controlled ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...
